In The Crucible who is the leader of the girls who cried out?

In The Crucible, Abigail Williams is generally viewed as
the leader of the girls. Abigail is the main driving force in the continuation of the
trials, and she gives the girls ideas for their testimonies. This representation of
Abigail is supported by the fact that she lies throughout the play, and her motivation
in crying witchcraft is to try to separate John Proctor (her lover and former master)
from his wife Elizabeth. Abigail is also the first one confronted about the encounter
with Tituba in the woods, and thus the first one to craft the girls' stories. In the
private conversation between the girls in Act I, it is clear that Betty is scared of and
intimidated by Abigail since she drank blood in the woods with Tituba. The girls' fear
of being labeled witches themselves is another factor that motivates them to continue
accusing others of witchcraft.
